To all whom z't may concern: n Be it known that I, CHARLES H. SCHUH?,

a citizen of the United States, and a res1-Y dent of the city, county,.and State of New York, have invented certain new and useful Improvements in Sectional Molds for Conrcrete Construction, of which the following is a ecification.

Thls invention relates` to apparatus for molding walls, partitions and other parts of 'what'are known 'as cement or concrete buildings.' As is well known in this art,

these concrete walls are generally constructed by first setting up a reinforcement, usually consisting of suitable horizontal and vertical steel or'other metal rods, sometimes fastened or secured together, and then providing on both 'sides thereof suitable tem porary forms or retaining walls which make up a mold into which is poured the cement concrete or other plastic and self-hardeningmaterial, in its semi-Huid state, which, upon hardening, forms the desired wall or the like, which may or may" not be provided' with a reinforcement as aforesaid, i After the cement or\ concrete has hardened, the temporary partitions referred to are removed and thewall smoothed or otherwise' finished.

As a rule, these temporary forms con-V stituting the mold-walls are built up to the height of one story, and after the molding operation and the hardening of 'the cement.

or concrete, they are, uponbeing removed, `again adjusted'for the molding of the wall of theinext succeeding story.

So far asI am aware, ordinary wooden framesare most generally emplo ed for vthis purpose these framesbeing ma e'of a pluf' ral-ity of slanke or bones-'which are cleaned,

clamped .or otherwise together in: .'pny, suitable temporary l nd,-whereby lthey maybe removed and again set up in 'another location..

' The princi-pal' ohject of the comprising a plurality of metal'units 'inthe form of plates, said unitsfbeing provided with means to facilitate their beingreadily assembledto form the side Walls of the rowed,

. met vention is the provlsion of a sectlonalmiold,

4 tionl of one thresfwill'sullic for all:

molds to which I have referred, and suitably secured together, said means also insuring the desired configuration d alinement of the mold as a'whole. -zii'erent sizes of units may be provided in order'to adapt the complleted mo dfor any desired length and heig 4t of concrete wall-section, and a u'rtherobject of the invention is to provide units of such a character that through the employment of simple auxiliary plates cor ners may be turned, the wall may be widened or narrowed either horizontallyor vertically, pilasters or columns may -be rovided for, and the system otherwise marie tosubstantially perfectly provide for all the requirements of the construction of walls of vthis character.

invention will be more readily underi stoo v by .reference tothe accompanying drawings, formlng apart ,of this specifica- Flgure 1v is a perspective viewof a sectional mold embodying my invention with `the parts thereof assembled andsome of them clamped or locked together;

Ashereinbefore su greeted, my mold comprises a plurality o "sections `of different4 l sizes but vcorrespondin about two feet square. T ese sections ar' i', best shown'in l in at fleastrone dimansion, the sections o the-samesize be'n identicalin allrespects.- Each sidewal n the mold is most largely made-up' .of a l v rality of sectionswhlch I refer'zshould) Y 1,`and a detailed Jdescrp--l'y e noo im anges of two or more plates are tig y clamped together, the plates `should lie in a right plane.

mensions of walls the body of the plate and Each of these sections is made up of a comparatively thin metal late 11 havin deformed corners, preferab y rounded, an which is provided around its entire edge with the rectangular flange 12. Where iron or steel is emp 'oyed for the plate 11, these flanges l2 are preferably provided by suitably securin D plate and t is at the present time .is preferred construction, but it will befall; parent that if other' metal is employed t e plate 11 may be integrally flanged.

It is of great im ortanee that these anges be rectangularly ispos'ed with reference to be as nearly true as possible. These placed edge to edge,

It is well known, of course, that the dias to 'len h and height and it .w1 be apparent that in order to provide a -mold for a wall of any given dimensions, a plurality of square sections, such as the plates 11, will either prove too short or too long for the desired purpose.J I' therefore provide a dier materially,

plurality of sections of the same height, but.

of less width, such as the section 13, so that I may thus provideva mold of any given length. It will be 13;; may-, f-by turmng the same -u on their sides, be'employed to vary the heig t as well as the length of the desired wall section.

Primari y for the purpose oftemporarily securing two or more of durin the process of provi e in each side these sections together assembling the' same, I Vflange of each section preferably two holes 14, one lo'cated near each I end" thereof .and these holes vbeingadapted toregister with corresponding 4ho es in the flange of another section when two sections are placed edge to edge'.- Through any pair of re 'ster-ing holes I insert a pin 15, the ends of w ich projectto each side ofi'thet'wojuxtaf posed flanges. I then employ a temporary or preliminary clampindeviee (best shown in Figs. 1 and 3) whic comprisesV u pair of wings 16 and 17, slightly wings being preferihl integrally 'mounted upon the handle-leverylS andf`each thereof rovided with the hook 19 at its extremity.

hese wings 16 and 17 are so disposed with reference to each other as to permit the hooks 19 to pass on the sides of the two juxtaposed flanges and ends of the in 15, ulcrum for e use 'of this clamping device as t nivel', the handle 18' beinhg forced 4towird the lates te tightly and` rmly wedge thgltwo anges, between the inclined inner of the wings 16 'and 17. In this manangle bars to the edge of the sired, to

plates are designed to and when the abut- 1n order that the sides of th .crete may practicallyV Y apparent that thesenarrovyer sections, suchas the section projections; third, that such inclined- "o'ig (j shaped with reference to each other, these around the projecting which pin provides afl ner', the two juxtaposed 'Hongos are tightly clamped together in an insured proper posltion, and, as suggested the plates 11 brought into n right plaue. bviously, as many 0f ese clamping devices 'may be employed as my be necessary or desirableto build up or assemble rthewall. While have referred to these clamping devices as being temporary or preliminary, .it will be apparent that they may be left upon the completed structure if degive additional strength and rigidity. For many apparent reasons, however, additional means should be provided to give rigidity to the structure and, furthermore, means "I 'st be rovided to ,retain the two walls 'at 'a fixed) and the desired distance from each other. Where tie-rods are etnployed, which ass acro the interior 'of the mold for tllie purpose of securing, the forms or side walls at a fixed distance from other, it will be apparent, tiret, that some prov1sion must be madefor the .removal of at least a portion of such rods, `e hardened conno projections of be finished and metal or other substances that such be to the smallest possi e extent interrogent with 'the employment of forms as oppositeV walls o f a inold in other words, that each side of the mold should as nearly as possible` a "lane dat surface, without undesirable depressions or,

bracm or retaining means shouldbe capable o .ready and easy adjustment and equally ready and easy removal when the mol mantled; fourth, that such bracing and retaining means should also tend to augment Athese temporary i remain; second, bracing 4or sufforting means must d is to 'be' disthe ri ldity of the entire structure through provi ing more dependable means clampingjthe sections together, through their flanges, as )well as bracing the two walls with reference to each other.

To accomplish the above, I provide a metal tube or sleeve 20, slightly less in for length than the desired width of wall, u

which, if desired, may be cured the vertical or'the horizontal-or bothmembers 'of the rods or bars'which make up the reinforcement to which-I have hereinbefore referred. or sleeve 20 is designed to remain. in the concrete when the latter hardens, and forms a part of said reinforcement, said tube or sleeve being completely concrete. A At each .end of said tube I 'provide the partly ta ering or cone-shaped washer 21 which, w en placed, at each end of said tube or sleeve, increases the length ofthe latterto the exact width of .wall desired, and, therefore, to the exact distance between' the opposite sectional forms.

lfastened or se- Therefore, this-tube` embodied in the `shown in 1 and designated by the nu meral 22), through which may be passed Y any desired form of tie-rod or tie-bolt.

fWhile I havel shown these plates provided with rounded corners, it will be apparent that While possibly not to so great an ex.

tent augmenting the strength of the plate, each of these corners may be diagonal, or, if rounded, a curve be rentrant or otherwise deformed, the essential idea being to prol vide an orifice at each common corner of the assembled sections. The tube or sleeve 20, with its abutting washer 21 is so located with respect to the plates, that the tie rod or bolt 23 may be passed through the orifice rovided at a common corner of the assemb ed plates and through said Washers and the tube or sleeve. One end of this rod 23 is provided with `The usual head 24, and the other end screw-threaded for the 'reception of the 'nut 25. Y

lI also provide, loosely placed over each end of the rod, a locking or .clamping Washer which comprises a plate26 which is provided with four lugs, in the form of two ,pairs of diverging` wings A27 28 and 29 3U.

The Wings 27 28 are spaced from the wings 29 30 a distance sufficient to accommodate of this locking device after theconcrete Wall has hardenedand it is desired to remove is provided in order to facilitate the removall vthe mold. It `will be-apparent that the endy edges of these Wings are located so close to the plate `11 that it would be d'iflieult to insert a Wedge orlever in order to pry the device from the flanges.V With the corners Anotched Aas shown, however, any suitable fori'n of lever may beemploycd, and'I find particularly desirable for this purpose one of the clamping levers 1S, lthe hooks 19 at the end of which may readily be inserted in this notch and the .looking device 2Greadily prled ol".

After the concret-e has been poured into they mold, and has Yhardened to form the wall, the nut 25 is unscrewed and the bolt or rod 23 removed, after which the'washer 26 may be easily detached and the mold dismantled. There now 'remains in the' wall the sleeve or tube 20 and the washers21 at each end thereof. The tapering configuration of each of these washers permits its 'being easily pried. out of its socket by any' suitable implement, after which said socket may be filled with concrete, Hush with the face of the wall, which has then an unbroken appearance, the sleeve or tube 20 being left permanently within the same as part of its reinforcement. Furthermore, the 'interior ends of these tubes 20 may be illed'with material which Will permit of the insertion and retentionof some form of fastening means for picture moldings, shelving and the like.

It Will be aparent that in. this manner I have provided) means for uniformly and rigidly spacing apart to' anydesiredf extent ,and bracing the walls of my mold, which at the same time serves to facilitate making rigid the entire structure through the vclamping washers 26, and which may be easily're moved what?. desiredand the 'Wall readily given a smooth and 4finished appearance. The temporary clamps 18may be either removed or permitted to remain after the side- Walls have been assembled and the permanent clamps 26 set.

To adapt my sectional mold for the construction cf corners, I provide'the outside wall thereof with an angle iron or bar 31, one leg or Wing of which is bolted to the flange of the plates running in, one direction and the other leg or wing similarly bolted to the flange of a plate running in the other direction. In this manner', a sharp and true outside corner may be provided, the edges` of the plates coming together to .render unnecessary the interposition of any auxiliary sections or members. For the ,.inside corner, .I provide a plate 432, to one edge of which is'suitably secured a wing otE the angle bar 33. The other edge of this plate 32 is similarly bolted to the Harige of a plate, While the other le or Wing of the angle bar 33 is similarly Wise suitably secured tothe flange of a plate running in the other direction. Obviously, 'an integral angle bar with one wideleg or Wing would suilice for the two-piece construction Which I have Iiust described. In

this manner, it will" be .apparent that through. the employement of my mold corner may be constructed Without difficulty. Ihave explained the manner in which I space Ithe Walls lof my molds Vapart simultaneously clamp the sections together at the common corner of each set of four plates.I Somewhati similar means are preferably employed to space thefip ates apartat the top edges of tlie .wallss ch means "bomprisin a U-shaped clamping .plate 34 (see Fig.

oltcd or otherwith one win longer than the other and the' shorter -wing provided with a suitable notch or recess to receive the vertical flanges. The ltop and lol'ger wing of said clamping plate 34.- is held down vsnugly against the top iian esl 12 of two of vthe plates 1l by means o the superposed leg. or Wing of the angle bar 35, the other wing 1of Which is held against the interior Wall of two of the plates 11. Through the ver tical wing of the angle bar 35 and through the U-shaped clamping' plate, which are' suitably apertured theretor, is inserted 'one of the tie-rods 23, havin nuts 36 at the 'ends thereof b means of w ich not only may the two top anges of the plates which are being clamped be brought into proper alinement and firmly and rigidly 'secured together, but the top edges of the two forms are spaced and braced ata proper distance from each other.

sis

Projections in the wall, for ornamental purposes or in order, for instance, to build the same around a pilaster or column which is wider than the desired width of wall throughout the major portion of its length, are provided for in much the same manner as that for turning a corner. By .reference to Fi .f 2, it will be seen that a plate 37 may be bo ted at one end to the vertical liange` of one of the plates and at the other end to the `vertical flange of a late which is olset from the plane of this side of thewall. Similarly, a corresponding plate 38 may be secured in the same manner to the lian es at the other side of the space which is esired for the projection referred to.

To brace my 'mold as a unit and hold the same in a proper vertical position, I prefer i port. The upper ends of each of t e rods' to employ the tension'rods 40, each of which is divided and provided with a turn-buckle 41, threaded into ,right and left screws on the sections of the rods 40 in theusual manner. The' lowene'nds of these rods 40 are provided with hooks adapted to engage suitable rings or hooks 42 A whichv may be provided in the tcmporary'ilooringor in any other r'i d sup.

40 is provided with a loop 39,' adapted to lie flat against the vertical portion of the U- plate 34, and through which the tie-rod'23 is #assed This tie-rod,"as hereinbefore set orth, is provided with screw threads at its ends whereby'the loop or eye 39 at the end of each rrbd 40 'may be tightly clamped 'by the nut 36, and thus not only rigidly secure the upper end of the tension rod 40, but provide a substantially continuous' brace extending both sides of the mold. It willbeapparent that the rods on either sideof the mold maybe individually tightened orloosened, in order to bring the mold as a unit into proper position land suitably brace the same 1n such position. Furthermore,- great ncety of. adjustment is possible inasmuch as 'these braces perform their functions through tension instead of compression.

In the construction of concrete residences or other smaller buildings, the walls are usually of the same width from one end to the other, but in warehousesfactories and the taller and heavier buildings an entirel different type of construction is employe These heavy buildings are usually put up in concrete in skeleton form the same as steel structures. Columns, beams and girders are run up, and afterward what are known as curtain walls are filled in which are much thinner than the columns. Inasmuch as it is desirable to have a concrete structure molded to form substantially one solid integral body throughout, it will be apparent that with my system the necessary increase or decrease in the thickness of the Wall may be readily made, so that in heavy construction I can run up the thin walls land the heaiy` columns simultaneously, producing what is purely monolithic construction. It 1s thought that because this would be almost impossible with the wooden molds now emplo ed, that this is the reason why heavy buil 'ngs arey run up in skeleton form.` v

From the above description it will he apparent that I have provided a sectional mold -for the purpose set forthwhich is not only well adapted to provide a solid and fairly completely finished wall, and which may be quickly and easilypset up and removed, but` which may -be adapted to an` almost endless, "aliety of conditions which confront the' builder of walls and partitions of this' character.,

'Many modifications of minor details of my improved sectional mold will doubtlessf readily suggest themselves. to those Skilled in the art to which it appertains,'partic. ularly modifications in the Vmanner of arranging -thc sections to change the coniiguration of the mold, and I therefore do not'.
